Answer: CDE can describe a minor arc, a major arc, a semicircle, or a chord, depending on the context in which it is used. Here are the definitions of each of these terms:
A minor arc is an arc of a circle that is smaller than a semicircle. It is named after the two endpoints of the arc. So, CDE would be a minor arc if it is a part of a circle.
A major arc is an arc of a circle that is larger than a semicircle. It is also named after the two endpoints of the arc. So, CDE would be a major arc if it is a part of a circle and spans more than 180 degrees.
A semicircle is an arc of a circle that is exactly half of the circle. It is named after the two endpoints of the diameter that it cuts. So, CDE would be a semicircle if it is a part of a circle and spans exactly 180 degrees.
A chord is a line segment that connects two points on the circle. It is named after the two endpoints of the segment. So, if CDE is a line segment that connects two points on a circle, then it would be a chord.
